The session will cover about Basic concepts of Object Oriented Programming with comparing along Structure Programming and Procedural Programming.

1. Object Oriented Programming
- Basic Concept

2. Why OOPs?
1. Procedural Programming
- Program executes statement by statement.
1. Structured Programming
- Modular programming(Help of Function)
1. Object oriented Programming
- Concept implemented with Classes & Object

3. Class
● Class is a template definition of the methods and variables in a particular kind
of object.
● Class created using the Keyword class
● Class name start with capital letter and can use Camel cases for name.

4. Object
● Object is the instance of Class. It used for access class methods and
properties.
● The object is created with the help of new keyword.
● Multiple object can create single Class.

5. Access Specifiers
● Public
- Publicly accessible from anywhere.
- Created using keyword public we will create variables and methods. By
default all method and properties are public.
● Private
- Scope is only inside particular class.
- Created using keyword private we will create variables and methods.
● Protected

6. Inheritance
● Accessing the properties and methods of one from another class.
● The keyword extends is used for extending base class properties.
● Types Of Inheritance
○ Single Level Inheritance
- Parent class methods will be extended by the child class.
○ Multilevel Inheritance
- Parent class method will be inherited by child class and again
subclass will inherit the child class method.
